Sweet Pics And Vids Of Bindi Irwin & Her Brother Robert That Show Off Their Sibling Bond

Has there ever been a closer family unit than the Irwins? The Australian wildlife conservationists Bindi and Robert Irwin — children of the late Steve Irwin, star of "The Crocodile Hunter," and his wife, Terri Irwin — have been best friends since Robert was born in 2003. Through their dad's death in 2006, their ongoing work with the Australia Zoo, and Bindi's own complete transformation, this brother-and-sister duo have remained closer than ever.

Bindi once shared a photo with her brother on Instagram in 2025, praising his achievements. "Robert, from conservation missions to television hosting, fashion runways to wildlife photography — your kind heart lights up the world," she wrote in part. Although the siblings are publicly supportive, they still have their occasional spats at home. In a 2024 appearance on "The Jess Rowe Big Talk Show," Robert revealed that they fight over "the most boring stuff ever." He added, "We argue about the most vanilla subjects. Like we'll literally be arguing about the morphology of some animal or prehistoric dinosaur or something. That is our family bickering."

After Robert was announced as a competitor on "Dancing With the Stars" in 2025, 10 years after Bindi won the dancing competition, he reiterated that the two don't compete with each other. "There is no sibling rivalry," he told People in 2025. "It's actually really nice. She has just said, 'Go into this and make it your own.'" It's obvious Bindi prioritizes family — the sentimental meaning behind her daughter Grace's name being proof — and Robert feels the same way. Other celebrity siblings, like Elle and Dakota Fanning, have an unbreakable bond as well, but there is just something about the Irwins' playful and genuine relationship that is different. And these sweet photos and videos of the duo prove it.

Bindi Irwin has a unique nickname for her baby brother Robert

When Bindi Irwin first met her brother, Robert Irwin, she tried to use her influence as an older sister to give him a different name. In a video of the moment on Instagram, a young Bindi tells her dad, Steve Irwin, "I think [...] I'll call him Brian." Steve simply replies, "His name is Robert."

Bindi says, "But I'll call him Brian for short." Steve only nods in response, clearly at a loss for words in front of his daughter, wondering how to convince her to go with Robert's real name. She's just too cute!

Robert Irwin (literally) leans on sister Bindi

Bindi Irwin uploaded childhood photos to Instagram on her dad Steve Irwin's birthday in February 2026, including one of the family exploring dunes. In the picture, it's clear Robert Irwin is obsessed with his older sister, even as a toddler. Steve leans into hugging Bindi in the snap while mom Terri Irwin holds a toddler-aged Robert in her arms for the family photo. However, instead of hugging his own mom, Robert leans way over to touch heads with Bindi, clearly wanting to just be close to her in a way that melts our hearts.

Bindi Irwin helps introduce brother Robert to wildlife

On Bindi Irwin's birthday in July 2025, her brother, Robert Irwin, shared a childhood photo on Instagram that serves as proof that Bindi helped foster Robert's love of wildlife. In the snap, Bindi holds a snake in her lap, reaching one hand to bring the head of the snake right up to her brother for a closer look. Robert sits next to his older sister, leaning over to stare at the snake in amazement. "Happy birthday to the best sister ever," Robert captioned the photo.

Bindi Irwin used to tower over brother Robert

Bindi and Robert Irwin dressed western chic in this beautiful childhood photo from way back when Bindi was still taller than her brother. She uploaded this throwback snap to Instagram in November 2025, where she's wearing a striped shirt with a mini skirt and knee-length boots. She stands against a wall with one arm behind her brother, who looks adorable with his bowl-cut hair, tiger shirt, and khaki pants. "He may not be my 'little' brother anymore but he'll always be about this big in my mind," Bindi wrote in the caption.

Now, Robert is a head taller than his sister Bindi

Bindi Irwin is no longer taller than her brother, Robert Irwin, but the siblings still have a close bond. The older sibling shared a cheeky photo on Instagram on Robert's birthday in November 2022, where Robert pretends to bump his head on a beam above them as Bindi points up at a sign that says "Watch your head" with a smug expression on her face. Oh, the perks of being shorter! Bindi praised "the taller Irwin sibling and greatest brother in the world" in the caption. 

Robert Irwin says sister Bindi inspires him

In May 2025, Bindi Irwin missed the family's Steve Irwin Gala due to medical issues. The oldest Irwin sibling had her appendix and 14 endometriosis lesions removed — this was after she had 37 endometriosis lesions and a cyst removed in 2023. She shared it all on Instagram.

Later that month, her brother posted a heartwarming selfie of him and Bindi in matching khaki, writing a message of praise in the Instagram caption. "Happy to see you on the up and up, Bindi," Robert Irwin wrote about his sister. "You face every hurdle head on, take it in your stride and inspire us."

Bindi is the most supportive sister of Robert on Dancing With the Stars'

Bindi Irwin was the proudest older sister to Robert Irwin when he competed on season 34 of "Dancing With the Stars" and won. In September 2025, Bindi shared a sweet selfie with her brother on Instagram before his debut dance, writing, "Tonight is the night!!!" 

Bindi, who won a Mirrorball of her own on season 21 in 2015, shared an emotional video on Instagram hugging her brother after his win. "Words can't describe how proud I am of you. You EARNED this," she wrote.

Robert and Bindi Irwin compare Mirrorballs

After Robert Irwin won the "Dancing With the Stars" Mirrorball in 2025, he took the trophy home to compare it to his older sister's from her win in 2015. In a January 2026 Instagram video, Robert and Bindi Irwin brag about their two trophies, playfully debating on whose is better.

"Mine's taller," Robert tells his sister in the video. She gives him a look and replies, "Yeah, but feel mine. Mine's heavier." This comment makes them both laugh. In a comment on the post, Bindi kept the joke going: "I'd say we're even, Brian," she wrote, using a playful callback to her former nickname for her brother.

The Irwin family loves khaki

Bindi and Robert Irwin are closer than ever as adults, and they continue to spread awareness for wildlife conservation. In this photo uploaded to Instagram in May 2026, Bindi, Robert, their mom Terri Irwin, Bindi's husband Chandler Powell, and Bindi's daughter, Grace Warrior, wear matching khaki as they pose for a family photo. The Irwins stand in front of an Australia Zoo sign, with a large cut-out of Steve behind them, smiling together. "As a family, we pour every ounce of passion, determination, and energy into our Wildlife Warriors work," she wrote in the caption.

Bindi and Robert Irwin have the sweetest sibling connection

Bindi and Robert Irwin's love for each other hasn't changed over the years. In September 2024, the duo recreated a photo together that they originally took in 2014, with Bindi smiling down at Robert in front of a beautiful scenic background.

For the newest picture, things have changed plenty. This time, it is Robert who towers a head taller than his older sister and smiles down at her. "Time flies!" Robert captioned the sweet post on Instagram.
